U s e only nails specified in this manual. The use of
any other nails may cause malfunction of the tool.
Do not permit those uninstructed to. use the tool.
Make sure no one is nearby before nailing. Never
attempt to nail from both the inside and outside at
the same time. Nails may rip through and/or fly off,
presenting a grave danger.
Watch your footing and maintain your balance with
the tool. Make sure there is no one below when
working in high locations, and secure the air hose
to prevent danger if there is sudden jerking or
catching.
6
,
On rooftops and other high locations, nail as you
move forward. It is easy to lose your footing if you
nail while inching backward. When nailing against
perpendicular surface, nail from the top to the
bottom. You can perform nailing operations with less
fatigue by doing so.
A nail will be bent or the tool can become jammed
if you mistakenly nail on top of another nail or strike
a knot in the wood. The nail may be thrown and hit
someone, or the tool itself can react dangerously.
Place the nails with care.
c
I
Do not leave the loaded tool or the air compressor
under pressure for a long time out in the sun. Be sure
that dust, sand, chips and foreign matter will not
enter the tool in the place where you leave it setting.
* D o not point the ejection port at anyone in the
vicinity. Keep hands and feet away from the ejection
port area.
7
*When the air hose is connected, do not carry the
tool with your finger on the trigger or hand it to
someone in this condition. Accidental firing can be
extremely dangerous.
Handle the tool carefully a s there is high pressure
inside the tool that can be dangerous if a crack is
caused by rough handling (dropping or striking). Do
not attempt to carve or engrave on the tool.
Stop nailing operations immediately if you notice
something wrong or out of the ordinary with the
tool.
Always lock the trigger, disconnect the air hose and
remove all of the nails before inspection, maintenance, relocating, or after operation is over.
8
z"
Perform cleaning and maintenance right after finishing the job. Keep the tool in tip-top condition.
Lubricate moving parts to prevent rusting and
minimize friction related wear. Wipe off all dust from
the parts.
When not operating the tool, always lock the trigger
by turning the lock knob (lock pin).

This trigger operated tool is intended for use only
when a work contacting element is not practical due
to the requirements of the application. Extreme
caution must be maintained not to point the
nosepiece of the tool in any unsafe direction. It must
be firmly held against only an intended and substantial workpiece.
Ask Makita's Factory or Authorized service center
for periodical inspection of the tool.

TOOL INSTALLATION INSTRUCTIONS AND USE
Lubrication
To insure maximum performance, install an air set
(oiler, regulator, air filter) as close as possible t o the
tool. Adjust the oiler so that one drop of oil will be
provided for every 50 nails.
When an air set is not used, oil the tool with pneumatic
tool oil by placing 2 (two) or 3 (three) drops into the
air fitting. This should be done before and after use.
For proper lubrication, the tool must be fired a couple
of times after pneumatic tool oil is introduced.

Loading nailer
CAUTION :
Always lock the trigger by turning the lock knob (lock
pin) 90" and disconnect the hose before loading the
nailer.

Load nails into the magazine so that the nail points
will be set into the groove at the bottom of the magazine. Move the nails into the ejection slot as far as they
will go.
CAUTION :
Always load the same type and size of nail into the
magazine. If you load the tool with different types
and/or sizes a t the same time, a malfunction may
result.

To close the slide door, slide it toward the driver guide until the slide door is locked by the leaf
spring.
Adjusting depth of nailing
CAUTION :
Always lock the trigger and disconnect the hose before adjusting the depth of nailing.
The depth of nailing can be adjusted by moving the
driver guide up or down. When moving the driver guide
to the higher position, you can obtain a deeper depth
of nailing; when moving it t o a lower position, you can
obtain the shallower depth of nailing. To adjust the
depth of nailing, proceed as follows:
1 . Remove hex wrench 3 from the hook.
2. Turn the adjusting bolt with hex wrench 3 until the
Hex wrench 3
adjusting bolt contacts the projection of the center
plate.

3. Loosen the three screws which secure the driver guide a half turn.
4. Turn the adjusting bolt until the desired depth of nailing can be obtained. The adjusting bolt
moves 0.7 mm ( 1 /32") per turn.
5. Tighten the three screws while holding the driver guide so that the projection of the center
plate contacts the adjusting bolt.
6. If nails are driven too deep even when the driver guide is set a t the lowest position, decrease
the air pressure. If nails cannot be driven deep enough even when the driver guide is set at the
highest position, increase the air pressure.

Nose adapter
CAUTION :
Always lock the trigger and disconnect the hose before installing or removing the nose adapter.
To prevent the workpiece from being damaged or
scratched, attach the nose adapter t o the end of the
driver guide.
When not using it, store it in either storage cavity in
the inlet cap.

Selecting compressor
The air compressor must comply with the requirements of ANSI B19.3 - 1981.
Select a compressor that has ample pressure and air
output to assure cost-efficient operation. The graph
shows the relation between nailing frequency, applicable pressure and compressor air output. Thus, for example, if nailing takes place at a rate of approximately
50 times per minute a t a compression of 6 kgf/cm2 G
(85 PSIG), a compressor with an air output over 29
literdminute is required. Pressure regulators must be
used t o limit air pressure to the rated pressure of the
tool where air supply pressure exceeds the tool's rated pressure. Failure t o do so may result in
serious injury to tool operator or persons in the vicinity.
Selecting air hose
Use a n air hose as large and as short as possible t o assure continuous, efficient nailing operation.
An air hose with an internal diameter of over 6.5 m m (1/4") and a length of less t h a n 20 m
(6.6 f t . ) is recommended. Air supply hoses shall have a minimum working pressure rating of
10.7 kgf/cm2 G (150 PSIG) or 150 percent of the maximum pressure produced in the system
whichever is higher.
CAUTION :
Low air output of the compressor, or a long or smaller diameter air hose in relation to-the nailing frequency may cause a decrease in the driving capability of the tool.

Connecting air hose
Lock the trigger. Slip the air socket of the air hose
onto t h e air fitting on the nailer. Be sure t h a t the air
socket locks firmly into position when installed onto
the air fitting. A hose coupling must be installed on or
near the tool in such a way t h a t the pressure reservoir
will discharge at the time the air supply coupling is disconnected.

Operation
Release the trigger by turning the lock knob. Place the driver guide agianst the workpiece and
pull the trigger. Nails will be driven into the workpiece. When nails are depleted, the trigger
cannot be pulled because a mechanism actuates. Load nails into the magazine, and the trigger
can now be pulled.
CAUTION :
.The mechanism cannot actuate when the slide door is open. So always lock the trigger by t u r n ing the lock knob t o prevent accidental firing when the slide door is open.
Operating the tool without nails shortens the life of the tool and should be avoided.
Air exhaust
Air exhaust direction can be changed easily by rotating
the exhaust cover. Change it when necessary.

Jammed nailer
When the nailer becomes jammed, proceed as follows:
1 . First, lock the trigger and disconnect the hose.
2. Remove the three screws which secure the driver
guide. Remove the driver guide.
3. Remove the jammed nail from the ejection slot.
To reassemble the tool, perform the above operations
in reverse sequence.
13
Hook
The hook is convenient for hanging the tool temporarily. This hook can be installed on either side of the
tool.
CAUTION :
.Always lock the trigger and disconnect the hose when hanging the tool using the hook.
Never hang the tool on a waist belt or the like. Dangerous accidental firing may result.
Nails
Handle nail strips and their box carefully. If the nail
strips have been handled roughly, they may be out of
shape or their connector breaks, causing poor nail feed.
Avoid storing nails in a very humid or hot place or
place exposed to direct sunlight.
14
I
Check regularly t o see if there is sufficient pneumatic
oil in the oiler of the air set. Failure to maintain sufficient lubrication will cause O-ring to wear quickly.

Pneumatic oil
Keep the air hose away from heat (over 60°C, over
140”F ) , away from chemicals (thinner, strong acids or
alkalis). Also, route the hose away from obstacle which
it may become dangerously caught on during operation.
Hoses must also be directed away from sharp edges and
areas which may lead to damage or abrasion to the
hose.
